Qedela ukuqala i-GeoXH, ngokucacile kwe-meter ngesikhathi sangempela

Akubonakali kukuthenjelwa, kodwa yilokho okushiwo yi-Trimble, i-GeoXH 2008 inikeza ukunemba kwe-sub-meter ngesikhathi sangempela.

Lokhu okokusebenza akubukeki kubi, okuvumela idatha ukuthi itholakale ngomakhalekhukhwini ngeziteshi zohlobo lwe-GNSS. Ukwengeza, isebenzisa i-Windows Mobile 6, i-wireless, i-Bluetooth namanye ama-picket... lapha kunokungabaza okuningi endleleni, njengoba kuqondwa ukuthi i-submetric ne-WAAS izoba se-United States noma e-Europe lapho kukhona okungakhokhelwa noma okukhokhelwayo. amasevisi... ukuze i-Latin America ingasho okuningi "isikhathi sangempela"

Ngokuqinisekile ungakwazi ukuhamba ngokushesha kakhulu kumaphrojekthi lapho lokho kuqondile kuwanele khona. Kuleli cala, izwe angadle ngabuhle obutheni noma yasemakhaya, akufanele ube nenkinga ukusebenza ngale ndlela, ngoba uma photointerpretation indlela yasetshenziswa, ne ephrintiwe orthophoto 1: 10,000 kuphela ipensela ukujiya Delineation njalo seliphindeke izikhathi ezingaphezu 5 amamitha Iphutha . Yiqiniso, ukuvukela emadolobheni, lapho omakhelwane balwela khona ububanzi bamasentimitha angu-15, kungcono ukusebenzisa ukuthunyelwa kwesikhashana.

Kuze kube manje angizange ngibone izixazululo eziningi ze-GPS ezingabizi ngezimiso ezingaphansi, ngaphandle kwe Imephu yeselula kusuka ku-Magellan, eyayicishe ibe ngu-$1,500 futhi ivumele ukunemba kwe-submetric kodwa ngokucubungula okuthunyelwe kusetshenziswa okokusebenza okufanayo njengesisekelo noma kusuka kwesinye isisekelo, kodwa njalo "okuthunyelwe".

Wona, Mobile semephu limane isiphequluli ngaphandle postprocessing ukufika 2 3 accuracies amamitha, kodwa ukulungisa umehluko ongafinyelela sub-imitha ukunemba. Akubi kakhulu ukuba nalezi zakhono kodwa ungalindeli ukuba nazo ngesikhathi sangempela.

Uma bengibuza ukuthi ngenzani ngeshibhile, angazi, ngangivame ukucabanga ukuthi angizange ngisebenzise isikrini sokuthinta, ukuthi anginayo i-Windows Mobile, hhayi i-wireless kanye nezinto kodwa izinguqulo ezintsha ze-Mobile Mapper CX ngezinye zezinto, kunalokho uthola okungaphansi kwe $ 2,000.

Yize uThales ebukeka eyilahlile i-Mobile Mapper Professional, ngoba manje bavele badideka iziphequluli futhi kubonakala sengathi bahlela ulayini obizwa ngeMM6 wokuthi uma kuqhubeka lokho emakethe kuzoba negagasi elihle, ngoba bakhuluma ngokuba neWindows Mobile 6 ngokuhlehliswa kokulungiswa okungafanele kokuthile. ngemali engaphansi kwama- $ 1,200 ... njengoba omunye umngani wami engitshela, umbono wokondla i-geodatabase ngesikhathi sangempela nge-SSM uyasebenza ... ngethemba ukuthi iyiqiniso (iThales), futhi mhlawumbe basinikeza ikhomishini yokunisela inhlebo.

O, bangibuza mayelana nentengo ye-Trimble GeoXH?

Ukusebenzisa Froogle, lokhu kubonakala kimi:

Alifanisi nothando lukamama ... kepha umbala ophuzi wobhanana muhle, hehe. Okwamanje ngizozinza nge-Mobile Mapper yami, futhi ngigcine ukunakekelwa okudingayo ngoba kubamba igciwane ngisho nomkhuhlane futhi bangibize u- $ 1,500.
